.08 x .5(x+100) = 73.2distribute the .5
.08 x (.5x + 50) = 73.2
multiply the equation in parentheses by .08
.04x + 4 = 73.2
subtract 4 from each side
.04x = 69.2
divide both sides by .04
Answer: x = 1730
Hope I helped! ;P

Solve for x
0.08 * 0.5 (x + 100) = 73.2
Distribute 0.5
0.08 ( 0.5 x + 50) = 73.2
Distribute 0.08
0.04x + 4 = 73.2
Subtract 4
0.04x + 4 - 4 = 73.2 - 4
0.04x = 69.2
Divide by 0.04
x = 69.2 / 0.04
x = 1730
0.08 * 0.5 (x + 100) = 73.2
Distribute 0.5
0.08 ( 0.5 x + 50) = 73.2
Distribute 0.08
0.04x + 4 = 73.2
Subtract 4
0.04x + 4 - 4 = 73.2 - 4
0.04x = 69.2
Divide by 0.04
x = 69.2 / 0.04
x = 1730

Times the numbers before the brackets together:
0.04(x+100) = 73.2
Then times out the brackets:
0.04x + 4 = 73.2
Re-arrange to get in terms of x:
0.04x = 69.2
Divide by 0.04 to get x on its own:
x = 1730
0.04(x+100) = 73.2
Then times out the brackets:
0.04x + 4 = 73.2

0.08 x 0.5(x+100)=73.2
0.08 x 0.5(x+100)=73.2
.04(x+100)=73.2
x+100=1830
x=1730
0.08 x 0.5(x+100)=73.2
.04(x+100)=73.2
x+100=1830
x=1730

0.08 x 0.5(x+100) = 73.2
0.5x + (0.5 x 100) = 73.2 : 0.08 = 915
0.5x + 50 = 915
0.5x = 915 - 50 = 865
x = 865 : 0.5
x = 1730
i hope it's right :D
0.5x + (0.5 x 100) = 73.2 : 0.08 = 915
0.5x + 50 = 915
0.5x = 915 - 50 = 865
x = 865 : 0.5
x = 1730
i hope it's right :D

0.08 * 0.5(x + 100) = 73.2
0.08 * (0.5 * x + 0.5 * 100) = 73.2
0.08 * (0.5x + 50) = 73.2
0.04x + 4 = 73.2
100(0.04x + 4) = 100(73.2)
4x + 400 = 7320
4x = 7320 - 400
4x = 6920
x = 6920/4
x = 1730
0.08 * (0.5 * x + 0.5 * 100) = 73.2
0.08 * (0.5x + 50) = 73.2
0.04x + 4 = 73.2
100(0.04x + 4) = 100(73.2)
4x + 400 = 7320
4x = 7320 - 400
4x = 6920
x = 6920/4
x = 1730

0.08 x 0.5(x+100)=73.2
0.08 x (.5x + 50) = 73.2
.04x + 4 = 73.2
.04x = 69.2
x = 1730
0.08 x (.5x + 50) = 73.2
.04x + 4 = 73.2
.04x = 69.2
x = 1730

0.08 x 0.5(x+100)=73.2 divide both sides by 0.04
x +100 = 1830 minus 100 on both sides
x = 1730
x +100 = 1830 minus 100 on both sides
x = 1730
2008-06-18 11:06 pm
x = -100 + 73.2/(0.08*0.5)
2008-06-18 11:05 pm
0.08 * 0.5(x + 100) = 73.2
0.04(x + 100) = 73.2
0.04x + 4 = 73.2
0.04x = 69.2
x = 1730
0.04(x + 100) = 73.2
0.04x + 4 = 73.2
0.04x = 69.2
x = 1730
